windeployqt does not collect the dll

Mikeeeeee

Hi!
Windeployqt does not collect the dll.
If you build in a 64-bit compiler, then nothing happens at all, and if in 32, I get this error when starting the program

MajidKamali

use windeployqt with --compiler-runtime switch
https://doc.qt.io/qt-5/windows-deployment.html

Mikeeeeee

@MajidKamali said in windeployqt does not collect the dll:

--compiler-runtime

--compiler-runtime do I need to write it in the command line or in qt when building the program?

Hi,

You need to read the documentation of windeployqt that @MajidKamali pointed you to. It's all there.

Mikeeeeee

There are no clear examples in the documentation, it is not understood. Apparently you have worked with this a lot and it is clear to you without documentation. How do I build the necessary dll files in a program with qml?

Mikeeeeee

Is there an example and explanation for this command?

windeployqt --qmldir <path-to-app-qml-files> <path-to-app-binary>

mrjj

@Mikeeeeee
hi
its a command line so you use it WITH windeployqt to say it must also copy compiler runtime
The error you showed looks like missing runtime for mingw compiler.

If you used QML also you will need to add --qmldir
where you point to the qml files you have.

so goto folder where your exe is and something like

windeployqt --compiler-runtime --release --qmldir C:\YOURPATH\qmlfolder MyApp.exe

or use full path to .exe also.

windeployqt --qmldir <path-to-app-qml-files> <path-to-app-binary>

Yes its ALL listed in the link
https://doc.qt.io/qt-5/windows-deployment.html

Mikeeeeee

There is no example for the link. There is only a scant description.
It's not work:

windeployqt.exe --qmldir E:\test\build-testQmlAndCpp-Desktop_Qt_5_14_1_MinGW_32_bit-Release2\testQmlAndCpp.exe  E:\QTProject\testQmlAndCpp\testQmlAndCpp.pro

It's too not work:

windeployqt --compiler-runtime --release --qmldir  E:\test\build-testQmlAndCpp-Desktop_Qt_5_14_1_MinGW_32_bit-Release2\testQmlAndCpp.exe

Is there a working example?

mrjj

@Mikeeeeee
There cannot be a working example as you must fill in the paths to fit your project.
also, you point to \testQmlAndCpp.exe for --qmldir but it must point to the folder where your actual QML files is.
Often the porject foler of the app, unless you put the files in a sub folder.

The link list the parameters and explain what each does. please read it.

Mikeeeeee

its too not work

windeployqt --compiler-runtime --release --qmldir   E:\QTProject\testQmlAndCpp E:\QTProject\testQmlAndCpp\testQmlAndCpp.pro

The documentation does not say what path-to-app-qmlfiles is.
Please explain in more detail how to use this command.

Mikeeeeee

and if I do this, then some libraries are written in the console, but they are not added to the folder with the. exe file

windeployqt --compiler-runtime --release --qmldir   E:\QTProject\testQmlAndCpp  E:\test\build-testQmlAndCpp-Desktop_Qt_5_14_1_MinGW_32_bit-Release

Mikeeeeee

it is work

windeployqt --qmldir   E:\QTProject\testQmlAndCpp  E:\test\build-testQmlAndCpp-Desktop_Qt_5_14_1_MinGW_32_bit-Release

mrjj

Well it could not as its where you place them.
Often in the project folder with the other files of the project.
